Be-itknwn-that I, WILLIAM BERTRAM 'BoLLEs, a citizen of'the-United States, residingat Milwaukee, in the county er-Mu- =waukee and Stateof-Wi'sconsin, have inventjed a new and useful Door-Lock-Operating Mechanism. 1

M invention 'relates toa device adapted tobe used in connection' with'lo'cksfor'securin' -;door s, -and -i in the "nature of a "mechanism "which "cooperates W1tl1 a, door "latch 'ordoor lock in sucha'manner asto permit'the latch or bolt-to be throw-n to such a position as to release the door when the deof this character are in the trade know as -anti panicdevices. inasmuch as their, pres- "ence upon -theudoorenables the door to" be "readily opened by'contact with thebody ofaperson fallingorpressing against the dei' iee,flthus'preventing any panic in the eflort ofone or more perscns to release the locking vice of my invention is operated. Devices mechanism for the door.

Generally speaking, the invention comprises the elements and the combinations thereof set forth in-the accompanying claims.

Referencejshould be had to the accompanyingdrawings formin'ga part of thiss'pecification inwhich Figure 1 represents an eleva- -Fig. K2 shows-the same device in sideeleva- "ti'on Fig. 3 is a plan view, and Fig. 4 is an e'd'ge View of the cover for-Iny device Fig. :5 shofwsin perspective a lock havinganoperating" -lever- -which- 'is adapted" to cooperate with "I'ny device.

device whichmay be used connection or in conjunction with locks that are; commercially sold. 1 These locks are adapted'tof be "used substantially with anyf'kindofdoor, and

1 one purpose of'thedevice of my invention is that t mayb ql eni ly mo n e p any door; "made to" cooperatewith the lock thereof. The casing which containsa" portion of the operating parts of my device is indicated at A, and upon the outside or face of'the casing there is mounted a lever B. This lever has an extending portion 1?.

which lies in front of the device and of the door upon which the device may be mounted in a posltion to be readily contacted eitherby the hand or body of a person/who may. ap-

proach the door. This lever B is mounted pivotally as indicated at U, and has a, por- Specification of Letters Patent. 7

The two springs and theparts K and K act to equalize the force applied to the-part D when the contact plate D is depressed, and

furthermore, actto equalize the pressure or force which results in returning the contact plate B to its initial or extended position.
